A billing schedule determines when the customer is billed for the services they receive.
You must specify billing schedules for each contract that you author in Oracle Service Contracts can be indirectly created from Oracle Order Management. You do not need to create billing schedules for such contracts.
Billing schedules can be defined at the contract header, the contract line, or the subline level.

Partial Period Computation
You can set attributes that enable the application to calculate billing for partial periods. A partial period duration is shorter than a full billing period duration, such as 10 days rather than a full month. It is a ratio of the number of days in the partial period to the number of days in the billing period duration (stream period unit of measure (UOM)).

The number of days in the billing period duration is based on the selection that is made in the partial period attributes Period Type. For example for billing period duration Month, if you select a Fixed Period Type, then number of days for any month is considered 30, but if you select Actual, then number of days for any month is the actual number of days as per the standard calendar. The application uses the Period Start attributes if service effectivity starts from the middle of a billing calendar period and ends in the middle of a billing calendar period. The Period Start attribute provides two options, Calendar and Service.

You can define partial period attributes at the operating unit level within Global Contracts Defaults.

Executing Billing Through Concurrent Programs
To initiate and complete the billing process, you must run the following concurrent programs:

1. Service Contracts Main Billing
2. AutoInvoice Import Program
3. Service Contracts Fetch Receivables Info for Billing

You should run contracts through the quality assurance check prior to submitting them for billing. This helps to ensure that the billing process is successful.

Note: As part of the Multi Org Access Control (MOAC), all billing programs process only those contracts that belong to the operating units that are listed by the security profile associated with the
current responsibility.
